With trac.util.presentation.Paginator this as become another powerful tool
for review and administrativ cleanup making direct access to Trac db obsolete
at many more occasions then AcctMgr allowed before.

Aug 10, 2011:

Continue to add a fake user session to enable use of sid column in Trac
db table session as foreign key as required by some db schemata (not SQLite).
This re-enables setting user attributes to Trac db table session_attribute
on registration time, i.e. for PostgreSQL compatibility. But beware,
the session added on registration is no longer marked as 'authenticated'.

I had to escape MS1 because our expanded camel case plugin trys to make
it a wiki link and it ends up displaying as "MS1?". But on systems
without that plugin, it displayed as "!MS1". By using lower case, it's
safe on all systems.
